As a result, the second band part (2) is pivotable relative to the first band part (1) between a closed position and an open position. The relative pivoting movement between the hinge bracket (3) and the first hinge part (1) about a first pivot angle (α) is limited to a first pivoting range and the relative pivotal movement between the hinge bracket and the second hinge part (2) is limited by a second pivot angle (α). is limited to a second swing angle range. According to the invention, the relative pivotal movement between the hinge bracket (3) and the first hinge part (1) is inhibited as a function of the first pivot angle (α) and the second relative pivotal movement between the hinge bracket (3) and the second hinge part (2) is dependent on inhibited the second pivot angle (α).

Description

  • The invention relates to a two-stage double joint hinge with a first hinge part, a hinged around a first pivot axis pivotally connected to the first hinge part hinge strap and a second hinge part, which is pivotally connected about a second pivot axis with the hinge bracket. The second pivot axis is aligned parallel to the first pivot axis and arranged shifted to this. Due to the pivotable mounting of the two hinge parts on the hinge bracket, the second hinge part can be pivoted relative to the first hinge part between a closed position and an open position. In this case, the relative pivoting movement between the hinge bracket and the first hinge part (first pivoting movement) is limited by a first pivoting angle to a first pivoting angle range. At the same time, the relative pivotal movement between the hinge bracket and the second hinge member (second pivotal movement) is limited to a second pivot angle range by a second pivot angle, the relative pivotal movement between the hinge bracket and the first hinge member (first pivotal movement) being inhibited in response to the first pivot angle and the relative pivotal movement between the hinge bracket and the second band member (second pivotal movement) is inhibited in response to the second pivotal angle.
  • An escapement is to be understood as meaning that the first or second pivoting movement experiences an opposing inhibition of an opening force (torque directed in the opening direction) or a closing force (torque directed in the closing direction). Here, the first pivoting movement and / or the second pivoting movement in each case at certain first and second pivoting angles is releasably held by the action of force. The inhibitions are each designed so that they can be overcome in any case by a sufficiently large opening or closing torque. Such a design is sufficient to provide a reliable control of the two-stage double hinge joint. This eliminates the need for additional control, in particular a tax bracket. The material saved in this case can be used to reduce costs and / or be used to reinforce the hinge bracket, so that it is possible to achieve a higher maximum load. The construction of the door hinge turns out to be particularly simple, since the inhibition of the first pivoting movement is exclusively dependent on the first pivoting angle and the inhibition of the second pivoting motion exclusively on the second pivoting angle.
  • With a generic double joint hinge, it is possible to provide concealed door hinges. Due to the design as a double joint of the door - even if the mechanical pivot axes are located within the door leaf or the door frame - are collided freely pivoted out of the door opening.
  • The disadvantage, however, is that such a double joint is mechanically indeterminate and has at least some opening angles a degree of freedom within which the joint is movable. As a result, a collision between the door and the door frame can not be excluded. As a result, a double joint hinge must always have a control.
  • For example, it is off EP 1 834 059 B1 known to completely prevent the second pivoting movement by a locking lever in response to the first pivot angle. Only when submitting a certain angle, the second pivoting movement is released.
    However, this technological solution is disadvantageous because the locking lever requires a high constructive and material complexity. The control bar - and the material used with it - is used solely for control purposes and does not contribute to the stability of the joint and its maximum load capacity. Furthermore, there is always the danger that the door hinge jammed and no longer closed or can be fully opened in not exactly worked control bars and the associated slotted guides, with contamination and wear.
  • Out DE 30 23 637 A1 is a double joint hinge is known in which the control of the two pivot axes is realized via an escapement.
  • Against this background, the invention has for its object to provide a two-stage double joint hinge, in particular for concealed arrangement on a door, which is simple in construction, can be produced more cheaply and has a higher load capacity compared to the prior art models with a comparable use of materials. The invention and solution of this problem is a two-stage double joint hinge according to claim 1 and a door according to claim 15. Preferred embodiments are specified in the dependent claims.
  • Starting from the generic two-stage double joint hinge, the pivoting movement of the hinge bracket is guided relative to the first band part (first pivoting movement) through a first circular arc-shaped track. In addition, the pivotal movement of the hinge bracket of the relative to the second band part (second Pivoting movement) guided by a second circular arc-shaped track. The respective raceway is used in particular for limiting the associated pivoting angle and possibly for supporting the hinge bracket. Depending on the intended use, the first track and the second track may be arranged in the axial direction (in the direction of the two pivot axes) on one or both sides of the hinge bracket.
  • In a preferred embodiment, the inhibition of the first pivoting movement is effective only in the region of the closing end of the first pivoting angle range. As a result, the position of the double joint hinge on reaching the closing side end in this position by force is releasable and also kept in particular clearance. Furthermore, the inhibition of the second pivoting movement is preferably effective only in the region of the opening-side end of the second pivot angle range, whereby the double-joint hinge is held releasably and in particular without play in a corresponding position by the action of force. At the opening end of the first pivoting angle range and at the closing end of the second pivoting angle range, the first pivoting movement and the second pivoting motion are unrestrained. In particular, the inhibition is designed so that it is effective only in one of the two end regions and the rest of the swing angle range is unrestrained to form a so-called freewheel.
  • The control of the double joint hinge according to the invention works on the principle that starting from a closed position initially the second pivoting movement arrested by the escapement at the opening end of the second pivot angle range and initially takes place only a change in the first pivot angle at an opening movement. Upon reaching the inhibition of the first pivoting movement or the closing end of the first pivoting angle range is a locking of the first pivoting movement by inhibition, while the locking of the second pivoting movement can be overcome by force. The opening movement can then be continued until the closing end of the second pivot angle range, whereby the maximum opening angle of the double-joint hinge is achieved. When closing the hinge behaves in the reverse manner, so that there is first movement in the freewheel of the second pivoting movement there alone, to then achieve after overcoming the locking of the first pivoting movement by this complete closure of the double joint hinge.
  • In a particularly preferred embodiment, the opening force (the torque directed in the opening direction) to overcome the inhibition of the first pivotal movement is smaller than to overcome the inhibition of the second pivoting movement. Further, the closing force (the torque in the closing direction) to overcome the inhibition of the second pivotal movement is smaller than to overcome the inhibition of the first pivotal movement. As a result, a clear control behavior is ensured in the transition region between the first pivoting movement and the second pivoting movement. Since the opening force to overcome the inhibition of the first pivotal movement is smaller than the opening force to overcome the second pivotal movement, it is ensured that initially locks the first pivotal movement at its opening end before the second pivoting movement is released. In the reverse direction of movement, it follows that initially the second pivoting movement is locked when closing, before the first pivoting movement is released again.
  • In a particularly preferred embodiment, the first swivel angle range is greater than the second swivel angle range. This makes it possible that in the most common application scenarios, in which the hinge must be opened only half the maximum opening angle or slightly beyond, an opening is made possible alone on the first pivoting movement. The second pivoting movement is therefore only switched on when particularly large opening angles are required. In particular, the first swivel angle range is dimensioned so that the inhibition of the first pivoting movement becomes active only at a swivel angle of 90 ° or more. Thus, an opening by 90 ° is possible in the freewheel, without the inhibition of the first pivoting movement is effective. For the user, the hinge according to the invention in this application scenario does not differ from a conventional 1-hinged hinge for concealed arrangement.
  • So that a freewheel of the first pivoting movement of 90 ° or slightly beyond is possible, the first pivoting angle range should be at least 95 °, particularly preferably at least 105 °, but at most approximately 120 °.
  • Moreover, the size of the first swing angle range determines the position in which a door wing secured to a door frame is locked after the first swing angle reaches the closing side end of the first swing angle range, but the second swing angle is not yet the opening side end of the second swing angle range has left. In this position, the Door automatically held open by the inhibition of both pivoting movements without additional doorstops or other locking devices are necessary.
  • In a preferred embodiment, the first pivoting angle range and the second pivoting angle range are in their sum (maximum opening angle) 180 °. Thus, a complete overturning of a connected door leaf is possible. At the same time, a collision of the door leaf with a wall frame surrounding the door frame can be avoided. Due to the 2-hinged design of the hinge according to the invention a concealed arrangement between the door and door frame is possible at the same time.
  • If a high vertical load of the double joint hinge according to the invention is to be achieved with relatively little material expense, it is preferably provided that in each case only one track is arranged in a double joint hinge with vertically aligned pivot axes on the first band part and the second band part. In this case, the track of the türzargenseitigen hinge part is formed below the hinge bracket, while the track of the door leaf-side hinge part is arranged above the hinge bracket. The raceway in each case forms a horizontally oriented and oriented towards the hinge bracket surface, so that in addition to the guide and a vertical support load can be transmitted to increase the overall support load.
  • In a preferred embodiment, the first raceway and / or the second raceway is formed by a groove open in the axial direction. The arranged in the direction of rotation ends of the groove serve as stops for the hinge bracket, while the radially inwardly and outwardly disposed flanks provide protection of the tread from contamination and interference. Moreover, a track in the form of such a guide groove can be produced particularly easily with cast parts or subsequently by machining.
  • Conveniently, the hinge bracket interacts by a first projection with the first track and / or by a second projection with the second track. The projection can in each case be formed in one piece from the material of the hinge bracket.
  • In a preferred embodiment, the first projection and / or the second projection on a paraxial (parallel to the pivot axes) arranged first pin or second pin, which is inserted into the hinge bracket. For this purpose, a corresponding bore or blind hole is provided in the hinge bracket. The formation of the projection by a pin is easy to implement and can be implemented in particular with the necessary technology for the production of the hinge axes. In particular, bores of the same diameter can be provided for the pivot axis and the pin, which can be provided particularly simply in succession by the same tool or synchronously by similar tools.
  • To reduce friction and prevent movement noise, the raceway interactive end of the pin may be capped or coated. Preferably, an engaging in a groove and this transverse to the direction completely filling plastic cap is provided. The material here is a dimensionally stable and low-abrasion plastic with low coefficients of friction such as POM (polyoxymethylene).
  • The position and the length of the first pivoting angle range are expediently determined by the design of the first raceway and / or the position and the length of the second pivoting angle range by the design of the second raceway. The ends of the raceways each form a stop over which the raceway interacting part of the hinge bracket can not be moved beyond.
  • In a particularly preferred embodiment, the inhibition of the first pivoting movement is formed by a first resistor arranged within the first track and / or the inhibition of the second pivoting movement by a second resistor arranged within the second track. In this case, resistance is to be understood as meaning a component which, depending on the respective associated pivoting angle and / or pivoting movement, provides an inhibiting torque which is directed counter to the pivoting movement, at least in individual cases.
  • In particular, the respective resistor has at least one control surface which adjoins the surface of the associated raceway flush with the surface and whose orientation differs, at least in sections, from that of the raceway. By a corresponding application of force to the control surface, a desired corresponding restoring torque can be provided. In order to achieve a freewheel in the other career, the surface is aligned perpendicular to the direction of force of the application of force.
  • Particularly preferably, the respective resistor has at least two opposite control surfaces. Thus, a resistance disposed near an end portion of a closing angle range can be made be used on the one hand to achieve, on the other hand, but also to inhibit leaving this end. In particular, the control surfaces are formed as two opposite wedge surfaces.
  • In a particularly preferred embodiment, the first resistor and / or the second resistor each have two asymmetric control surfaces, in particular wedge surfaces. This results in a different resistance force, which is exerted when the inhibition is exceeded in the closing or opening direction. As a result, the opening or closing behavior of the two-stage double joint hinge can be adjusted specifically.
  • In a particularly simple embodiment, the first resistor and / or the second resistor are each formed by an elastically deformable molded body. The interacting with the track and the resistance part of the hinge bracket can be rigid and immobile. The application of force to generate the resistance then feeds from the elastic deformation of the molding. In particular, an elastic material (an elastomeric plastic) can be embedded as a bead of material in the raceway flush.
  • In a particularly preferred embodiment, the first resistor and / or the second resistor is formed in each case by a spring-loaded threshold. The threshold may on the one hand be integrally formed from the material of the track, when the interacting with the raceway portion of the hinge bracket - in particular a pin - spring-loaded in contact with the track or the threshold is held. It is also possible that the threshold consists of a separate component which is inserted into a recess of the track and biased by a spring in the direction of the hinge bracket. Such a separate threshold is particularly preferably formed from POM and is put under tension by a separate spring steel spring.
  • The hinge bracket preferably has a U-shaped configuration (in a sectional plane lying perpendicular to the axial direction) with a first leg hinged to the first hinge part, a second leg hinged to the second hinge part and a connecting region connecting the first leg to the second leg. The first leg and the second leg are formed substantially straight, wherein the first leg is arranged parallel and displaced in the longitudinal direction to the second leg. In particular, the connection region is formed at least for the most part of a straight portion, wherein the two legs and the straight portion, or its extension, form three sides of a parallelogram. The inner angle of the parallelogram opposite the articulation of the first leg on the first hinge part corresponds to the size of the first closing angle range. This leads to a particularly space-saving design of the hinge. As a result, when the opening-side end of the first closing angle range is reached, the hinge bracket comes to rest in parallel on a wall of the door hinge. With a complete opening of the hinge, the second band part is offset relative to the first band part by the parallel displacement of the two legs to the outside, so that the door leaf can be opened further.
  • The invention also relates to a door with a door frame and a door leaf, characterized in that the door leaf is pivotally connected to at least one two-stage double joint hinge as described above with the door frame. In the closed state, the double-jointed hinge is concealed between the door leaf and the door frame.
  • The invention will be explained below with reference to only one embodiment illustrative drawings. It shows schematically:
    • 1 a built-in two-stage double joint hinge according to the invention in its open position,
    • 2A an axial plan view of the arrangement according to 1 in the closed position,
    • 2 B the presentation 2A in an intermediate position,
    • 2C the representation from the 2A and B in the open position,
    • 3 a perspective view of a vertically cut two-stage double joint hinge according to the invention in its closed position and
    • 4 a detailed view 3 ,
  • In the 1 the installation situation of a two-stage double joint hinge according to the invention is shown in its open position. The arrangement is cut open for better understanding in the horizontal direction. The two-stage double joint hinge according to the invention has a first, multi-part band part 1 , a second, also multi-part trained band part 2 as well as the first band part 1 with the second band part 2 connecting hinge strap 3 on. The first band part 1 is in a hollow profile of a door frame 4 used and a first vertically extending pivot axis x 1 pivotally connected to the hinge bracket. The pivoting movement is - as in the horizontal section of the hinge bracket 3 is visible - over a first hinge pin 5 realized. Analog is the second band part 2 around a second horizontal pivot axis x 2 via a second hinge pin 6 swiveling with the hinge hanger 3 connected. Furthermore, the second band part 2 with a hollow profile of a door leaf 7 connected. Both the door frame 4 as well as the door wing 7 have a fold in the embodiment shown 4a respectively. 7a on. As a result, the construction of a concealed door hinge is expensive, since a collision in particular between the door rebate 7a and the door frame 4 must be avoided.
  • Due to the pivotable connection of the hinge bracket 3 with the first band part 1 and with the second band part 2 can the second band part 2 opposite the first band part 1 between one - in 2A shown closed position and a in 1 and 2C pivoted open position shown.
  • The hinge hanger 3 has in the illustrated horizontal section on a U-shaped configuration. It includes one to the first band part 1 hinged first thigh 3a , one to the second band part 2 hinged second leg 3b as well as the first leg 3a with the second leg 3b connecting connection area 3c , The first leg 3a is parallel and displaced in its longitudinal direction to the second leg 3b arranged. The first leg 3a as well as the second leg 3b are essentially straight while the connection area 3c has a stepped shape. Due to the steps in the closed state, a collision with the first band part 1 and the second band part 2 prevented even with a particularly compact design. In the open position are the first leg 3a and the second leg 3b approximately parallel to a wall frame enclosing the door frame and to the door leaf 7 arranged. As a result, the space within the door hinge is optimally utilized. These correspond to the internal angle at the transition between the first leg 3a and the connection area 3c or between the connection area 3c and the second leg 3b the maximum first swing angle α 1 or the maximum second pivot angle α 2 ,
  • By a first, as open in the axial direction groove within the first band portion 1 Trained career 8th is the pivoting movement of the hinge bracket 3 relative to the first band part 1 (first pivoting movement) controlled and limited. In this case, the hinge bracket in a first pivoting angle range between its closing end, which in 2A is shown, and an opening-side end - visible in the 1 . 2 B and 2C - be moved. The angle between the closed position - in 2 B indicated by dashed lines - the hinge bracket and its current position is referred to as the first pivot angle α 1 . The swivel angle at the opening-side end of the first swivel angle range, ie the size of the first swivel angle range, is 105 ° in the exemplary embodiment.
  • Accordingly, the relative pivotal movement of the hinge bracket 3 opposite the second band part 2 through a second career 9 controlled and limited, which as open in the axial direction groove in the second band part 2 is trained. The hinge hanger 3 is relative to the second band part 2 around a second swing angle α 2 opposite to in the 2A and 2 B visible closing end of the second pivoting angle range pivoted. The second swing angle α 2 At the opening-side end of the second swivel angle range is 75 °, so that a maximum opening angle (sum of the size of the first swivel angle range and the second swivel angle range) of 180 ° results. How to get in the 1 and in the 2C can see is the door 7 in the open position relative to its original position ( 2A) swiveled through 180 °.
  • According to the invention, the first pivoting movement is exclusively dependent on the first pivoting angle α 1 inhibited and the second pivotal movement exclusively in response to the second pivot angle α 2 inhibited. This will be the hinge bracket 3 held at the opening end of the first pivot angle range and at the closing end of the second pivot angle range such that by force (torque) can be done a solution of the lock. In the remaining first or second swivel angle range, the first and second pivoting movement is substantially uninhibited, so that there is a freewheel. The inhibition of the first pivoting movement and the inhibition of the second pivoting movement is via a first spring-loaded threshold 10 or a second spring-loaded threshold 11 realized.
  • The operation of the spring-loaded sleepers 10 . 11 is in particular a comparative consideration of 3 and 4 can be seen in which the double joint hinge according to the invention is opened by a vertical section. There is visible that the hinge hanger 3 each with one from a pen 12 . 13 and a cap 14 . 15 formed projection in the respective associated career 8th . 9 intervenes. The reason of the trained as a groove career predominantly has a perpendicular to the pivot axes x 1 . x 2 standing level extending ground, with a flat surface of the caps 14 . 15 in contact. The two pens 12 . 13 are axially parallel in holes of the hinge bracket 3 arranged.
  • The two spring-loaded sleepers 10 . 11 are each formed by a dimensionally stable threshold body, the top surface flush with the bottom of each guide 8th . 9 followed. At the broken side of the first band part 1 is also recognizable that the local emerging body 10 on the underside of a spring element 16 is supported.
  • If at a first pivoting movement the cap 14 through the first running groove 8th She passes through her bottom with the top of the threshold body 10 in contact.
  • To provide the inhibition are at the top of the two threshold bodies 10 . 11 Control surfaces arranged in the form of oppositely inclined slopes. These exert an inhibiting force in both an opening and a closing movement due to the spring load. According to the variant shown, the pitch of the slip direction acting in the closing direction and in the opening direction is asymmetrical. This ensures that the achievement of the respective end locking position is easier than leaving. This contributes to the safe control of the two-stage double joint hinge, after which in an opening movement starting from the closed position ( 2A) the first pivoting movement about the first pivoting angle α 1 initially at the opening end of the first career 8th locks in place ( 2 B) and only then the second pivoting movement by leaving the detent position on the second track 9 is released. After pivoting about the second tilt angle α 2 then can the full opening position ( 2C) be achieved. The intermediate position in which both locks are active ( 2 B) can be used in particular as a rest position in which the door leaf 7 locked at least against minor external influences.
  • The detailed view 4 moreover discloses that the cylindrically symmetrical cap 14 (and analogously 15 ) with their side surfaces on the flanks of the career 8th respectively. 9 providing grooves lie flat. The transition to the newly formed bottom of the cap 14 (respectively. 15 ) is chamfered, so that during a pivoting movement of air and / or arranged in the groove lubricant within the raceway 8th . 9 at the cap 14 . 15 can be passed. The top of the cap 14 is formed with a collar, which in a corresponding groove on the upper edge of the grooves 8th . 9 intervenes. This allows a safe and precise guidance of the hinge bracket 3 be achieved.
